To aZZ whom it may concern;

Bert known thatI, EU ENE SCHNEIDER, a

citiZeIl of the Republic of Franc-e residing at 42,,Rue dAnjou, Paris, France,; have in-z vented new and useful Improvements in] Thisinvention has for itsobjectto provide. an improved construct on of a gun mounted on ajdouble-trailed gun carriageiofthetype described; in my application filedJune 9th,v

Like the gun described in my ia-boveementioned -application the improved gun of the, present inventloncomprises a wheeled axle,

that is anaxle A and two wheels The carriage head C v is fired to the, wheeled axle during firing.

The divergible trails F which .carry the anchoring devices at theinrear .ends are.

capable of assuming inclinedpositions relativelv to the combination constituted by the wheeled 'axle B--A-'-B and the carriage head C. i

In the illustrated example the possible inclination oi the trails is'obtained by mount the carri'age'heacl as fwellas a rocking axle] for the combined saddle and gun pedestal Gr tor-producing the longitudinal uprighting of 55 the said pedestal. i

I The .pivot. .pin g' of the gun pedestal Grtcarrylng the gun barrel). is formed bytwo trunnions that project respectively from the upper side and the lower side ot-the saddle- The longitudinal uprighting of the coinblned saddleHand gun pedestal G' is pro duced by the inovernent of two toothed secv torsh formed onthe said saddle, meshing with pinions C .fiXed on a cross shaft 0 carried by the carriage head C. This shaft carries externally a worm wheel sector "C that is actuated by .means of a worm C ournalled in the. carriage head C. The worin C is" driven by meansot gearing C C -C -C 770 The carriage head'Q together with the saddle H. and thegun pedestalG-inay be up righ td transverselyby oscillation around. aii axle Jcarried in a bracket A fixed to the axleLA. This oscillatory inotion is produced a by the rolli-ngof a worm C over a worm wheel sector A? carried by. the bracket-A This worm C .is fixed on a shaft C journalled in. the carriage head C. This shaft C is driven by means of gearing'CH The training movement of the gun pedestal G isxp ro d feed by the rolling movement of a worm G1 over a w'oriuwheel sector H carried by the saddle H1. .a

This worm "G is fixed on a shaft Gr journalled in the gun pedestal G; it receives its motion through gearing G?.G G-".- G G G$..-

The elevation of'the cradle S carrying the 9Q gun. barrel isp-roduced by the movement of 1 the toothed :s'ector R1 around a pinion G fixed on a shaft G carrying a worm wheel G which is actuated by a worm G that receives its. motion through gearing G G G The kinematic connection between the trails: F ,is effected in the known manner by means of a cross rockingbeam F tulcrumed at its. centre by means of a ball and socket joint 7 on a cylindrical'pivot pin C formed on the carriage head C.

The cross beam F carries at itsendsball and socket jointsF to which-are articulated the lower ends of two arms F whose upper ends .F are fixedto the trailsF and are fitted 10:3 upon the ball "and socket joints 0.

One of the. essential characteristic teatures of -'-the improved construction which constitutes an improvement applicableto all the constructional forms described in my above-mentioned application, consists in the peculiar arrangement of a device for balancing the rocking mass, and in the manner of its connection to the carriage head, said connection being made in such a manner as to facilitate the longitudinal uprighting of the combined saddle H and gun pedestal by rocking around the axle 0 The device for balancing the rocking mass around the cradle trunnions s, in the elevating of the gun, comprises two cylinders K pivoted to the said cradle by means of trunnions k and in each of which a piston K is adapted to move.

A spring L is coiled around the rod K of this piston. This spring bears at one end against the piston, and at its other end against one of the ends of the cylinder K.

When the'cradle and the gun barrel are in their horizontal position, the spring L is pressed and kept stressed by the fact that the free end 74 of the piston rod K is attached to the carriage head by means of a cable or metal band M fastened at one end m at c whilst its other end 'm is attached to a cross beam N which is fulcrumed at its centre by means of a stud n in the carriage head C.

The cable or band M is guided by a pulley 0 movable around an axle pin 0 carried by the gun pedestal G. In order that the pull upon the rod K shall act always along the axis of this rod, the cable or band M before passing over the guiding pulley 0 passes under a boss G projecting from the gun pedestal G.

hen the parts are in the positions indicated in the figure, that is to say, when the cradle is horizontal the effort that tends to cause the oscillating mass to turn downwards by rocking on the trunnions a, is balanced approximately by the tension of the spring L which has a tendency to cause the mass to rock in the opposite direction with a leverage equal to the distance between the piston rod and the axis of the gun cradle trunnions. The result is that the displacement of the elevating sector R over the pinion G can be effected without the necessity of exerting any considerable force.

At the same time, the illustrated apparatus allows of balancing the mass that rocks around the axis 0 for the uprighting movements of the combined gun pedestal G and the saddle H, which allows of producing without any appreciable exertion of force, adisplacement of the sectors it over the pinions C As a matter of fact the pivotal movement of the combined gun barrel, gun cradle. gun pedestal and saddle H around the axle (2 has a constant tendency to take place with an efl ort represented by the product of the weight of the oscillating mass multiplied by a leverage equal to the distance between the vertical line passing through the centre of gravity of the said mass and the axis 0 In the uprighting movements, this effort is approximately balanced by the action of the balancer. It is for this purpose that the piston rod K is coupled to a band which, instead out being attached directly to the carriage head, passes over a guide pully carried by the gun pedestal. .Moreover, the coupling of the piston rod, as above stated, is effected by means of bands attached to the ends of the cross barN pivoted on the gun carriage head; this allows of a suitable action of the balancer irrespective of the training positions.

I claim:

l. A double-trailed wheeled gun mounting comprising a gun carriage head, a saddle pivotally mounted in said carriage head, a pedestal pivotally mounted on said saddle, a pivotal axle supporting said saddle in said carriage head, said axle constituting the axis around which the saddle and pedestal oscillates, the ends of said axle projecting externally from the carriage head to form two spherical joint elements for the articulation of the trails thereto.

7. In a device of the class described, the combination of a carriage head, a gun saddle, an axle supporting said saddle in said carriage head, a gun pedestal supported by said saddle, training mechanism for said pedestal, and a balancer for the saddle and pedestal, said balancer being adapted to operate in all the training positions of the pedestal.

8. In a wheeled-axle gun mount, a carriage head mounted on the axle, means for moving said head about an axis at right angles to said axle, gun supporting means mounted in said carriage head, and a balanoer whereby the longitudinal uprighting of said gun supporting means is facilitated.
